Answer:

OPTION C

Step-by-step explanation:

We have the following rules:

$ \sqrt[a]{x} = x^{\frac{1}{a} $    and

$ x^a . x^b = x^{a + b} $

OPTION A: $ x \sqrt[7]{x} $

= $x . x^{\frac{1}{7} $

= $ x^{1 + \frac{1}{7} $

$ = x^{\frac{8}{7} $ $ \ne x^{\frac{9}{7} $

So, it can be eliminated.

OPTION B: $ \bigg ( \frac{1}{\sqrt[7]{x}} \bigg )^9 $

= $ \bigg ( \frac{1}{x^{\frac{1}{7}}} \bigg )^9 $

= $ \bigg ( x^ {\frac{-1}{7}} \bigg )^9 $

= $ x^{\frac{-9}{7}} $

So, this option is also eliminated.

OPTION C: $ x . \sqrt[7]{x} $

= $ x . x^{\frac{1}{7}} $

= $ x^{1 + \frac{1}{7}} $

= $ x^{\frac{9}{7}} $

So, OPTION C is the answer.

Hi! Please help me find the slope of the line.
lana66690 [7]

Answer:

3/2

Step-by-step explanation:

We can use the slope formula to find the slope of the line

m = ( y2-y1)/(x2-x1)

Using the points (0,-4) and (2,-1)

m = ( -1 - -4)/( 2 - 0)

   = (-1+4)/ (2 -0)

   = 3/2

Answer:

100% = 60

55% = 33

80% = 48

35% = 21

Step-by-step explanation:

9 ÷ 15% = 60

60 x 100% = 60

60 x 55% = 33

60 x 80% = 48

60 x 35% = 21

hope this helps :)
